PYROTECHNICS.

Specification of Letters Patent.

Patented Jan. 17, 1911'.

Application filed March 31, 1910. Serial No. 552399.

To all whom it may concern:

ties which extend appreciably beyond the Be it known that I, HENRY J.PAIN, a citiinner side of the plug 13 within the auxilzen of the UnitedStates, residing in the borough of Manhattan, city, county, and State ofNew York, have invented an Improvement in Pyrotechnics, of which thefollowing is a specification.

My present invention relates to pyrotechnics and particularly to a flashapparatus adapted for use in marine, military or other signalingoperations or in target practice at night or-in pyrotechnic displays orin divers other ways.

The apparatus made in accordance with my present invention preferablycomprises an initial or primary flash cartridge, means for igniting thesame, a plurality of other or secondary cartridges, and means forconnecting the primary and plurality of secondary flash cartridges insuch a manner that the said cartridges may be fired successively atpredetermined intervals, as hereinafter more particularly described.

In the drawing, Figure 1 is a partial central cross section andelevation of the apparatus comprising my present invention, and Fig. 2is a perspective view of a modified form thereof. I

Referring to the drawing and particularly to Fig. 1, the devicecomprising my invention consists in a primary flash cartridge in dicatedat a and a plurality of secondary flash cartridges, each of which isindicated at b, all of which cartridges are connected as hereinafterdescribed.

The primary cartridge a preferably comprises a casing or wrapper 10which may be of a general cylindrical configuration as shown in Fig.1,or of any other desired con figuration, and is preferably made oftarred paper, but may as will be understood, be constructed of any othersuitable material. lVithin the wrapper 10 is an open-ended cylindricalmember 11 preferably made of pasteboard and over which the wrapper 10 isclosely wound. Within the cylinder 11 1s v an' auxiliary cylinder 12 andthis auxiliary cylinder 12 may also be made of'pasteboard or any othersuitable material.

At one end of the auxiliary cylinder 12, a plug 13 of insulatingmaterial is fitted and leading into and passing through this plug 13 arecircuit wires 14, which as will be understood, are properly covered withsuitable insulation exteriorly of the plug 13 but which are bared attheir inner extremiiary cylinder 12. Leading into the cylinder 11 thereis also a fuse 15 which as will be understood may be of any ordinary construction.

The auxiliary cylinder 12 is approximately filled with meal powder 16,it being understood that any suitable ignition powder may be employed tofill the auxiliary cylinder 12. The space within the cylinder, otherthan that occupied by the auxiliary cylinder 12 and fuses, issubstantially filled with a flash powder indicated at 17.

1S designates a time fuse made in any well known manner extending intoand embedded within the flash powder 17 in the cylinder 11 and as isindicated in Fig. 1, the auxiliary cylinder 12, the fuse 15 and thefuse18 may be conveniently secured t0- gether by a strip or tape indicatedat 19 or any other suitable means for accomplishing this purpose.

Each one of the secondary cartridges preferably comprises a wrapper orcasing 20 constructed similarly in all respects to the casing 10 of theprimary cartridge as hereinbefore described. In each secondary cartridgethere is also a cylindrical member 21 made from a tube of pastcboard orsimilar material, withinv which is a charge of flash powder indicated at22. I

The time fuse 18 extends from the primary cartridge (1. through each oneof the secondary cartridges 1) and within each of these sccondaiycartridges Z) I may provide an auxiliary fuse as indicated at 23,leading from the time fuse 18 and extending into the flash powder Thehereinbefore described apparatus may avires 14 to a suitable source ofelectricity and closing the circuit, or may be fired by hand by lightingthe fuse 15, and that the fuse 18 may be so made and the secondarycartridges I) placed thereon in such spaced apart positions that thecartridges may be fired at any predetermined intervals.

By reference to Fig. 2, it will be seen that instead of employing theapparatus as shown in Fig. 1, I may extend the corresponding 7 tube,flash. powder within the tube, means.

1 primary fcartridge that the same may be l atube, flash'powder gralmeansextending through and so conends of the casings or wrappers of thecartridges to bell-shape configurations'as indicated at.25 surroundingthe receptacle or envelop 26 containing the. flash powder referencenumeral 28 in this figure representing the circuit Wires by means ofwhich the primary cartridge mav be fired electrically,
